Variety has reported that actor Christopher Evan Welch, the voice of Miles “Tails” Prower in The Adventures of Sonic the Hedgehog cartoon series, has passed away at the age of 48*. Welch voiced Tails in all 65 episodes of the series alongside Jaleel White’s Sonic and Long John Baldry’s Robotnik (Baldry passed away in 2005).

Welch’s other TV credits include AMC’s Rubicon, The Sopranos, The Practice, Law & Order: Criminal Intent, Law & Order: SVU and The Good Wife. Welch also appeared in several movies including Spielberg’s War of the Worlds and Lincoln, Paul Thomas Anderson’s The Master and Woody Allen’s Vicky Cristina Barcelona.

As a Sonic fan who tape recorded every single episode of the series as they aired, Welch’s death really is heartbreaking. His voice acting really shaped the character of Tails in those early days when he was a silent sidekick in the games, and was relegated to a smaller role in the Saturday morning Sonic series. All of us at Sonic Retro send our thoughts to Welch’s family and friends.

*Despite many entertainment outlets stating that Welch was likely 48, this doesn’t jive with his child-like voice in Adventures of Sonic the Hedgehog. At 48 now, Welch would be 28 in 1993. But given puberty has been the presumed cause for Welch not appearing in Sonic Christmas Blast in 1996, he would have been closer to 11 which matches with a 1983 birthdate floating around. And yet, the Seattle Times shows a photo from 1993 featuring a man much older than 11. So either Welch was much older and could do a great child voice, and did not appear in the Christmas special for other reasons, or something else is not matching up.
